Agra, May 12 (PTI) Here's some good news -- a study on the impact of atmospheric pollution on the Taj Mahal has allayed fears of any chemical reaction of airborne particles on the marble structure.
The study, undertaken by Archaeological Survey of India as part of a UNESCO-funded project, proved that "no calcium sulphate or calcium nitrate particles were found in harmful proportions in the Taj's ambience", ASI sources here said.
The study was carried out in the air pollution laboratory of the ASI by assistant superintendent archaeologist Deepankar Banerji.
The study, however, did not look into the impact of sand-carrying winds from Rajasthan's desert that are said to have a "sandpaper effect", damaging its smooth outer surface.
